AWS Documentation and Drift AWS already provides a getting started guide in the Amazon FreeRTOS documentation. But, when I was following it trying to get the demos to work I was unsuccessful. After a bit of investigation it became clear that the documentation was out of date. Following submission of feedback to AWS the documentation was promptly updated with up to date information. Now, the Amazon FreeRTOS is a very active project and is changing continously.

There are multiple options for running an Nvidia GPU mining rig to mine cryptocurrency. You can use Windows or multiple flavors of Linux. I tend to use Ubuntu for most of my Linux needs, and so I used it for my rig as well. Initially I wanted to use a completely headless install with only a CLI system. I didn’t see a need for X. That didn’t work out because the Nvidia driver and the customizations required to overclock the GPUs required X.

Update 2018: This is now probably outdated and it never really worked 100% anyways. It is now possible to store games on external media. So, I’m not using LANcache anymore. Update: Multiplay LANcache on Github I recently picked up a PS4 and having been out of the gaming scene for a few years was a bit shocked to see the size of game downloads and updates off the PSN Store.

While messing around with my Polar H7 trying to figure out how to read real time heart rate information I inadvertently overwrote the device name. I didn’t even realize that this was possible, but apparently it is. When running an hcitool lescan I would no longer get the device name listed. I was getting a weird character. This made life a bit harder. On my Android devices when scanning for the device I’d just get a blank name.

I recently picked up the Polar H7 Heart Rate Sensor (Bluetooth Low Energy). The long term goal is to connect up the sensor to my HTPC running XBMC so that I can see my heart rate on the screen while I work out. I usually work out to music playing on the HTPC or watching P90X videos. So, it’d be nice to be able to see the heart rate information real time as well as record it in a file/db for historic purposes.
